The Weber Kettle Grills have been a main stay for me for decades. The easy of use to the quality is outstanding.  The 18" is perfect for daily grilling, for my family of 3. My 22" is ideal for long and slow cooking like ribs or larger cuts of meat. I can also put on the vegetables. Utilizing the air flow through the top and bottom dampers, I have complete control of the heat and time. Propane is fine but charcoal is what grilling is all about. Webers line of Kettle Grills are the only way to grill.
